Using this case is very easy and works with Raspberry Pi Model A, Model B rev 1 and Model B rev 2. Snap the Pi into the case bottom for a secure press-fit. If you want to poke around you can leave the top cover off. If you want to protect your Pi, fit the cover on, it will fit securely so you can put the Pi into your book-bag without worry. There’s a slot for a GPIO ribbon cable so you can connect a Pi Cobbler while the cover is still on, and remove it easily as well by popping the top off. Please note: this case is not compatible with our low-profile microSD card adapter.
